Analytical model of low mass strange stars in 2+1 spacetime

Abstract

The low mass compact stars are quite fascinating objects to study for their enigmatic behaviour. In this paper, we have modeled this kind of low mass strange stars based on the Heintzmann ansatz [1] in (2 + 1) dimension. Attractive anisotropic force plays a significant role to restrict the upper mass limit (which is comparatively low) of the strange star. We have applied our model to some low mass strange stars. Our model could be useful to predict the important parameters of the low mass strange stars.

Spinor solutions of a Chern–Simons model for the superconformal algebra

“…Three-dimensional theories of gravity have a very rich structure of black hole solutions with matter: polytropic stars from [4], rigidly rotating perfect fluid stars [5], low mass strange stars based on the Heintzmann ansatz [6], circular thin shells in 2+1 F(R) gravity [7], exact solutions in (2 + 1)-dimensional anti-de Sitter space-time admitting a linear or non-linear equation of state [8] and references therein.…”
